段とを具備する方向探知機。[Claim for Utility Model Registration] The receiving output of the direction measuring antenna is captured in a time-divisional manner at a level corresponding to the arrival direction of the received radio waves, and the received signal captured in the time-divisional manner is detected by a receiver, In the direction finder, the detection output is supplied to a direction indicating section to indicate the direction of the incoming radio wave, and the output of the receiver is supplied to a sound receiving section to receive a modulated signal in the incoming radio wave, A variable level adjuster inserted in series between the receiver and the sound receiving section, and detecting the output level of the receiver for each switching section in synchronization with the time-sharing acquisition of the antenna reception output. and supplying the detection level of each switching section held in the level detector as a control signal to the variable level adjuster in synchronization with the time-sharing acquisition. A direction finder comprising control means.
